This post is a follow-up to our previous case study on incorporating unit testing into an existing team’s development environment. The case study is based on a real solution that has already started reaping rewards for our client, and is gaining momentum. We’re now looking at making it easier for the development team to maintain this test suite, and proposing some extensions – including a form of tagging.

Why Incremental Delivery Is Good
Incremental delivery is a key component of most software projects today – it allows us to deliver the most valuable elements of a system first, which allows our customers to start getting benefit from the system earlier. As additional features are developed, and additional use cases are enabled, they are delivered to the customers, who get incremental value from those features. This can have a significant impact on ROI projections for a project – and can be the difference between getting the deal and losing it.

iRise – software prototyping tool
We received a comment from Tom Humbarger at iRise on an earlier post, which led us to take a look at their site. iRise provides a tool for rapid prototyping of web-based applications, and there’s an overview of the products available. They have iRise Studio which allows people to create […]

Describing the Software Development Process
Software development involves determining what to develop, documenting this decision, determining how to develop it, and actually developing it.We present a framework for describing this process in terms of layers of activity. Many people use pyramid analogies, which show the magnitude of effort in each layer (lines of code versus lines of requirements, for example). Many other people use inverted pyramids to reflect the importance (or impact) of work done at different layers (a sentance defining a strategy has more impact than a line of code). Some people show PERT diagrams of waterfalls or pretty circular arrows charts showing iterative lifecycles, or any of many good analogies.

Take this poll or we’ll shoot this kitten
[Ed: If you read Tyner Blain via RSS you have to visit the site to vote in the poll. Also, we’ll use a camera.] An earlier post on CRUD use cases started a fantastic debate (both public and private) about what it means to write great software, and if it’s […]

From MRD to PRD: The key to defining a spec
They key to writing a great spec is knowing how to specify software that mets our customers’ needs. It can be a daunting task. First, we have to define what our customer needs. High level requirements are just requirements that are too vague or high-level to be directly actionable. “We […]

Where Bugs Come From
In the Foundation series article on software processes we introduce a definition of software process as three steps – (decide, develop, deliver). That article will provide some contextfor this discussion, which dives more deeply into the three steps (decide, develop, deliver).

Foundation Series: Unit Testing of Software
Testing software is more than just manually banging around (also called monkey testing) and trying to break different parts of the software application. Unit testing is testing a subset of the functionality of a piece of software. A unit test is different from a system test in that it provides information only about a particular subset of the software. In our previous Foundation series post on black box and white box testing, we used the inspections that come bundled with an oil change as examples of unit tests.

Brainstorming – Making Something Out of Everything
Previously, we talked about brainstorming as one of the best elicitation techniques for gathering requirements. Here are some details about how to facilitate a general brainstorming session with a group of people in 5 easy steps (and then another 5 easy steps). Seven to ten people is a good number […]
